Failed to resolve: com.google.firebase:firebase-core:15.0.0

Question

I have a strange issue when integrate firebase:

Answer 1

if you integrate firebase automatically from tools, The new version of android studio have strange bug, the software inserts

    implementation 'com.google.firebase:firebase-database:16.0.1:15.0.0'

instead of

    implementation 'com.google.firebase:firebase-database:16.0.1'

fix this line (remove numbers after last ':')
